Intelligent navigation control method for five-prevention lock of transformer substation

Abstract

The invention relates to an intelligent navigation control method for a five-prevention lock of a transformer substation. The method comprises the following steps that (1) an operator simulates an operation order according to a dispatching command, a first step operation task is displayed on a display screen in form of text after simulation, and meanwhile, an arrival path taking a simulation screen as a starting point and taking a unit of the first step operation task as an ending point is given and broadcast by voices; (2) a computer key automatically analyzes equipment to be operated after reading the operation task; (3) an intelligent navigation system guides the operator to walk to the entrance of a current control room; (4) a position comparison module is added in the computer key, and a prompt about whether operation can be executed or not is given in form of text and voice according to a comparison result. The method is scientific in design and high in practicability, the shortcomings of a conventional transformer substation are overcome, and the safety is improved; in addition, information about equipment in the transformer substation can be stored zonally and hierarchically, so that the method is simple and efficient.

Description

technical field [0001] The invention belongs to the technical field of electric power, and relates to a technology for preventing misoperation of a substation, in particular to a five-proof lock intelligent navigation control method for a substation. Background technique [0002] In the substation of the power system, the five-proof locking system is currently the most widely used and most practical measure to prevent electrical misoperation. But present computer key has following defect in use process: [0003] 1. With the advancement of the construction of unattended substations and substation operation and maintenance stations, coupled with the commissioning of new substations, multiple operating personnel who were on duty in a fixed substation need to be there, and they are not familiar with the implementation of switching in the substation.

AI Technical Summary

Problems solved by technology

[0003] 1. With the advancement of the construction of unattended substations and substation operation and maintenance stations, coupled with the commissioning of new substations, multiple operating personnel who were originally on duty in a fixed substation need to be present. They are not familiar with the implementation of switching in the substation. Gate operation, the same problem is more prominent for new employees, which will directly lead to a lot of time wasted when looking for operating equipment, reducing work efficiency

[0004] 2. When the five-proof lock is placed in the wrong position, if the operator does not carefully check whether the five-proof lock corresponds to the locked device after opening the lock, electrical misoperation accidents may occur, and the consequences will be disastrous

[0005] 3. Unpredictable possible dangers and precautions during operation

[0006] Through the search, no relevant published patent documents were found
